If you're not sure what the differences among an espresso doppio, a cappuccino, and an americano are, this hilarious video from Mental Floss will sort it all out for you. By the end, you'll understand 27 popular types of coffee you'll see on menus anywhere, and hopefully have discovered something you'd like to drink.

The beauty of the video is that you really don't need to be a coffee snob to love it and appreciate it—Mental Floss' approach is pretty grounded and a lot of fun to watch. Beyond that though, almost every type of coffee in the video is something you can get at any coffee shop in any neighborhood, including your local Starbucks, and those fast food chains that are dabbling in fancy coffee drinks. At the very least, you'll understand exactly what you're getting (or should be getting) when you order a "Frappe" or a "Macchiato," At best, you'll see something you like in the video and decide to give it a shot the next time you grab a cup of coffee.
